Adjacent angles
Their angles of intersection are the same, and the angles facing each other are supplementary.
Perpendicular Lines form right angles at their point of intersection
The angles opposite one another at the intersection of two lines are called vertical angles. Vertical angles are always equal in measure, meaning that if one angle measures 40 degrees, the angle directly opposite it will also measure 40 degrees. This property is a result of the way the lines intersect, creating pairs of angles that are congruent.
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
Perpendicular lines
Lines in a plane that cross each other are called intersecting lines. When two lines intersect, they do so at a single point, known as the point of intersection. The angles formed at this intersection can vary, and the lines can be either parallel (never intersecting) or non-parallel (intersecting at some angle). Intersecting lines are essential in geometry and help in understanding various concepts such as angles, shapes, and the properties of polygons.
Lines that intersect to form right angles at their point of intersection have slopes that are negative reciprocals.
